Miami Dolphins waive three players

DAVIE — The Miami Dolphins got a head start on the Aug. 31 cut-down day to 75, by waiving running back Tristan Davis, nose tackle Travis Ivey and tight end Kory Sperry before practice Monday.

Sperry, a free agent signing last year from the Chargers, played eight games for the Dolphins in 2009, including one start. However, once the Dolphins re-signed tight end David Martin before training camp Sperry's days were numbered.

Davis , a free agent signing out of Auburn last year, spent a few months on the Dolphins' practice squad. This season he was competing for the role as kick returner, however, he misplayed the opening kickoff against Tampa in the first exhibition game and ended up rolling around in the muddy infield, a picture caught by Sport Illustrated.

Ivey, an undrafted rookie from Maryland, was in the hunt at backup nose tackle. He, too, was captured in a recent Sports Illustrated photo when he wore several sets of shoulder pads after practice as part of a rookie hazing.
